rIhis invention relates to iushing devices for closets and hasparticular relation to those closetsv which have a di'erential controlfor the flushing water.

In cities where the shortage of water is liable to be acute, surveyshave revealed the fact that the greatest amount of water is usedy foriushing of closets. It has alsoV been determined that much water couldbe saved if the closets were all provided with means whereby a greateror lesser amount could readily be admitted to the closet bowl,depending` upon the purpose tor which the i flushing was desired.

The primary object of this invention is the provision of an improvedcloset iushing device having a differential control for the flushingwater.

Another object of the invention is the pro- '2'0 vision of an improvedcloset flushing device having two valves of the standard type and soplaced as to normally maintain the same static pressure.

Another object of the invention is the provision of an improved closetflushing means having separate spaces to deliver water to the respectivevalves.

Other and further objects of the invention will be apparent to oneskilled in the art from a reading of the complete specification andclaims.

Referring to` the drawings wherein I have illustrated my invention,

Figure 1 is a front cross sectional view of one form of my invention.

Figure 2 is a front view of a modified form.

In Figure 1, 10 designates the wall of the tank which contains two waterspaces .11 and 12. y A

The wall 10 is of a tank of the low-down type. It is also adapted, ofcourse, to other types.

The water space 11 is of a relatively large capacity and is used todeliver a relatively large amount of water for flushing purposes when acomplete flushing is desired. The water space 12 is' relatively smalland is intended to deliver a relatively smaller amount of water when asmaller amount is needed.

Serial No. 399,350.

The water spaces 11 and 12 are separated by a partition 18 having anopening 14 lat a height not too great for the water to reach when thewater space 11 is filled in a manner to be described. l

At the left in Figure 1 is the intake or inlet control device which Ihave designated 15. I/Vithin this control device 15 is a suitablevalvewhich may be of any well known or suitable type to be found on themarket. A

tube 16 supplies water from thewater supply as thevalve within thecontrol device permits. This water passes out from the tube 17 into thewater space 11. As the water level rises, in the water space 11, to apoint where itwill pass through the opening 14, the water space 12 isalso filled with. water.

To prevent overiow of the tank, the inlet valve within the controldevice 15 is connected L Y to a lever 18 fulcrumed at 19 and connectedat its moving end by a link 2O which is in lturn connected to a lever 21`iulcrumed at 22. On the end of this lever 21 is a fica-t ball 23 `whichrises as the level of the water rises. The relative positions of thefloat-ball 23 and valve are such that the iioat-ball 23 will not closethe valve untilboth water spaces are full.

As the water iiows into the water space 11.-, a small stream passesthrough the pipe 24 and is emptied inte the safety overflow pipe 25 torefill thebowl to bring the water to the proper normal level. f

h-e overtlow'pipe 25 has a passage which leads into the bowl directly,whereby if for any reason, the inlet valve fails to operate, thel tankcannot overiiow. As has already been stated, the pipe 24 reiillsthebowl, the

water passing down the upright pipe 25,

through the lu-connection 26 and into the pipe 27 which connects to thecloset bowl.y p

At the ltop of the pip-e 27 and -opening into it is a valve openingwhich is normaliy ciosed by the bulb valve 28. T his bulb valve 28 isprovided with a stem 29 which is held lin upright posit-ion by a guide30 supported from a support 31, at the upper end of the stem 29 is aloop 32 and therebelow is a sliding lifting member 33. The liftingmember e 33 is provided with an eye 83 which surrounds the stem 29 andengages the loop 32 during the lifting operation. The lifting member 33is pivoted at its upper end to a lever 34 which is fulcrumed at 35. Thelever 31 has an operating handle 36 by which the bulb valve 28 is liftedto start the flushing operation.

In the smaller water space 12 are located elements similar to those justdescribed. An outlet L-connection 126 with a valve opening is connectedwith a passage to a pipe 127 which leads to a pipe 27 which, as alreadystated, leads to the bowl.

The bulb valve 128 is normally seated on the valve seat and is providedwith a stem 129. A guide 130 is supported by a support 131 from theoverflow pipe 125. A lifting device 133 is constructed similar to thelifting device 32, already described and engages the loop 132 on the endof the stem 129, when the lifting devicel is lifted. The lever 134,fulcrum 135 and handle 136 are respectively similar to the correspondingparts 341, 35, 36, already described.

In operation, the water space 11 iills` first, the water thenoverflowing through the opening 14 into the smaller water space 12.IVhen the smaller water space 12 is filled, the ball 23 will shut offthe intake supply and the two water spaces will remain full. It is to benoted that from this condition with the valves 28 and 128 having thesame static water pressure and'being connected to the two water spaces,respectively any one of three results may be obtained. (1) If it isdesired to give the closet a small flushing, the handle 136 is operated.(2) If a full flushing is desired, the handle 36 is operated. If aneXtra large flushing is desired, both handles 36 and 136 are operatedeither simultaneously or successively, without permitting sufficienttime between the two operations, for the first one operated to empty itsWater space.

By using applicants invention, it is possible to construct the waterconnections with substantially all standard parts which may be purchasedin the open market.

In the construction shown in Figure 2, a flanged T-connection 201connected to a source of water supply. To this T-connection 201, areconnected pipes 202, 202, Flow regulating valves 203, 203W are providedfor regulating the flow of water.

Controlled by the operation of the handles 204, 2041a are valves whichcontrol the admission of water from the water spaces within theconnections 205, 205% These valves are located within the fixtures 206,206l which are connected to the upper ends of the respective pipes 207207, These pipes 207, 207a connect at their lower ends to the pipe 20Swhich has au outlet 209 leading to the howl of a closet.

The valves which are located in the castings 206, 206, respectively andare operated by the handles 204, 204, are of the usual lio-tank,slow-acting flush valves. In practicing my invention, however, one ofthe valves is preferably set so as to permit a smaller amount of waterto pass in one operation than will pass during an operation of the othervalve.

.Vhile I have illustrated and described embodiments of my invention, Idesire to have it understood that I do not limit myself to the exactshowing and that modifications and changes may be made without departingfrom the spirit of the invention and within the scope of the appendedclaims.

Having described my invention, what I claim and desire to secure byLetters Patent is 1.
